The end of 2012 I bought a BeQuiet power supply (not listed here, because this is already No. 2), because the old (noname goods) after more than 6 years the spirit abandoned: The computer did not start by pressing a button or only very rarely. This first BeQuiet NT was doing good service, however, came after a short time to Spulenfiepen when the computer was more stressed (2-3 months). After about a year, the start up difficulties ("Be Quiet Bug") about February 2014 came back then the computer under full load just went out. Convinced of the virtually non-existent running noises of BeQuiet NT, then it should be this here: BeQuiet Pure Power CM BQT L8-CM-730W. Well, what can I say? After about 2 months, the Spulenfiepen began under load again (one can cope with) and after 8 months to increased start-up difficulties. Against March this year came even to the fact that the computer indeed started off and booted but now and then the graphics card yielded no picture. One took the computer for several minutes from the grid, he could start again with image usually after 1-2 attempts. This piling up more and more, so I decided to just one year, again to buy a new power supply. According to the survey among friends my Enermax has now recommended at this time, because some many years (in some cases for almost 10 years) use such power supplies with no problems.
Conclusion: The "Be Quiet Bug" has struck again. Spulenfiepen under full load occurs after a short time and the overall life of BeQuiet power supplies does not seem to be greater than 1-1.5 years, until it comes to deficits. Hands off.
